BEDSTEAD LOCK.

T 0 all whom it may concern.

Be it known that we, Hnxnr J. IIOIUY'IOH and EDMUND A. STEINMAN, bothresiding at Chicago, Cook County, Illinois and both citizens of theUnited States, have invented certain new and useful improvements in aBedstead Lock; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

ur invention relates to metal bedsteads and in its general objectsincludes the pro-- viding of simple means constructed chiefly of sheetmetal for affording the operative connections between various parts oi;the bedstead at the corner posts.

11 one aspect, our invention aims to provide a socket constructedchiefly of sheet metal and adapted to be secured to a tubular bed postwithout employing screws or bolts, to provide a socket of this classwhich will permit the end rail of the bedstead to be attached directlyto the same, and to use the sockets at the same end portion of abedstead as means for connecting a stiffener to this end portion. Italso aims to provide strongand inexpensive sheet metal rail endsarranged for interlocking with these sockets; to arrange theinterlocking so that it will be augumented by the action of gravity andso that the extent of the intor-locking will be controlled by theengagement of each said end piece with the adjacent socket, and to allowthe parts automatically to interlock to an increased extent in making upfor Furthermore, vide simple means for preventing the thrust of such arail end piece against a bedpost or a socket mounted on the bedpost fromspreading the parts of the end piece out of their normal relation toeach other.

In another aspect, our invention aims to provide a combined side railand spring construction in which the side rails are slidably insertedintocollars or end pieces afilording the operative connections both to isockets on the bedpost and l the tilting to the bars between which thespring or bed-bottom is stretched, to provide shoulders upon these endpieces engaging the side rails to limit of the end pieces by the tensionof the spring or bed-bottom, and to provide cheaply constructed buteffective means upon the end pieces for limiting-the insertion of wearon the parts. our inventlon aims to pro- Application filed June '7,1920, Serial No. 386,967.

the end rails into the same. invention aims to provide simple means forpreventing a rotation of non-cylindrical side rails when used with suchend pieces and to provide an unusually rigid, neat and cheaplymanufactured end piece construction. 530 also, our invention aims toprovide an end piece construction which will readily permit theattaching of the same to the bars between which the bed-bottom isstretched. and desirably to provide this attachment to the bars throughpart of the means which prevent the end piece from spreading. Stillil'urther and also more detailed objects will appear from the followingspecification and from the accompanying drawings, in which Fig. 1 is asomewhat diagrannnatic'elevation showing a side view of portions of abedstead and illustrating the manner in which the tension of thebed-bottom holds the end pieces upon a side rail of the bedstead.

Fig. 2 is an enlarged and fragmentary llurthermore, our

vertical section through a bed post and the Fig. is a perspective viewof the rail end or connecting member of the previous figures, togetherwith a portion of the elliptically sectioned side rail associatedtherewith.

Fig. 6 is a perspective view of a simplified form of the supportingmember or socket carried by the bedpost and used. in connec tion withtheconnecting members. of Fig.

Fig. 7 is a view (on a. reduced scale) of the sheet metal blank fromwhich the main part of the socket of Fig. 6 is formed.

Fig. 8 shows the sheet metal blank from which the connecting member ofFig. 5 was formed.

In accomplishing the purposes of our invention after the mannerillustrated in the drawings, we first secure to each post of thebedstead a socket member including a transverse pin freely spaced fromthe post, then mount a hook member upon the adjacent end of the siderail of the bedstead and interlock the hooks of this member with thetransverse pin on the socket member.

Both of these members are preferably constructed of steel and preferablydesigned so that they can be manufactured chiefly by punch; pressoperations, thereby reducing their cost and insuring uniformity parts.

To use our invention in connection with bedsteads having tubular cornerpostssuch as the hollow cylindrical posts of the drawings, we tirstpunchan aperture l in each o'l the posts along the inner face of the post,namely the t-ace directed towards the side rail of the bedstead. Then weprovide a corresponding .iaperture I3 inthe back l of the socket, whichback is curred to snuglyllit the post 2 and which back has a pair ofwebs (5 extending from its opposite edges and disposed in verticalplanes. These "webs are preferably parallelto each other andjointlycarry a horizontal pin 5 extending transversely oi the webs. T hesocket, asthus constructed of a single and forked-metal plate and a pinor cross-bar, is held against the post or? the bedstead with theperforations .l. andv 3 in alinementwith each other, after which .iinsert the bent shank '7 oi i-sheet metal keytl'irough. these *alinedperforations into the bore oi the post ,2 and lock this key in positionby means of awedge'8 after the" manner shown in Fig. This wedge tents todraw the bent shank of the key further into the post, thereby drawingthe enla ed heads 9 of thekey against the outer iacc oi? the Cir back '4of the socket so as to secure this socket firinly tothe post with thecross-bar 5 in avlixed position predetermined by the location of "theperforation '1 intheypost. Thus arranged, each oil' the said socketsforms a supporting member projecting inwardly Oct-thebedstead fromthenpost carrying that socket and each socket presents its cross-bar ina convenient position for receiving a suitable downwardly directed hookformation on. the adjacent entl of a side rail oi the bedstead. l l herethis'rail is tobe independent o'l the bed spring we desirably providethe needed hooking formation in a tube arranged afterthe mannerdisclosed in our co-pending application u 1 i i .f i. ;386,968 on abedstead lock and stlfiener, as filediby us onilune 7; 1920. i

It the side rails or thebedstead are also to form. a permanentlyconnected part of the frame for the spring or bed-bottom after themanner which has become customary in recent years, we first assemblethese side rails 13 in connection with the bed-bottom 'l'lvand theconnecting pieces or book members 15, as for example aft'erfthe mannershown in Fig. 1. Thisffigure shows the ends of'the side rails '18 asslipped respectivelyinto the hook members 15, the pair of end piecesintended for each-end of the bedstead being connected to each of themanner shown inl igs. 2 aud t).

the back 4: of the a'c ent jlllblle collars or hook members 15 forpreventing the end rails 13 from sliding entirely through the sameitwill be obvious from Fig. .1 that the tension of the springs i? willhold the hook members or end pieces on the side rails so that no othertas- 'teniugs will be required to retain the various parts "inproperrelation to each other when the resulting metal-trained bedbottom. member is detached tromfthe ends oi the bedstead.

ills a desirable constriiiction for such a hook member or end piece, weo-desrrably form the latter of sheet-metal with'a sub stantiallyll-shaped transverse section-atfording a rounded bottom forthe-elliptical side rail '13, after the manner shown.- in the drawings,by starting from a blank shaped as in mg. 8. Then "we bend end laps lhfrom the-two shanks o 'l 'the tLse'ctinned. end piece towards each otherand butt \veld the tips of these shanksmoeach other. XV e also(flesh-ably connectthe free ends ol the 'U-shaped metal piece to eachother by means not a strap .19 which is "here shown as tal-shaped and asareas to the shanks or this hook men'iber. This strap 19 has a centralperft'oration 3(l 't'or receiv ing abolt Bil by'meansof which the strapis bolted to :the vertical web of *the angle bar 16 to which the:resilientb'echbottom is attached (aftertheflm-annerof Figs. '2 and i)the central. portion of the strap 19 is flush with vertical shoulders 32on the metal sides 22 ottpthe hooknnembeiu so that the strain due tot-hetensioning o-fxthe bedlilOttO DJ. is received by these shoulders andnot'by the rivets'20. A I

To prevent the side rail 13 from sliding entirely through the "bore; ofthe end piece, we arch'oneend of'the latterupwardinto a riser -formation21. somewhat after the Then we provide each ot'th'e sides or sha-nks 22d-fi theU-sectioned hook member slots 23 extending lromthe same endofthis member as the riser projection 21, these slots being desirablycurved upwardly j so as to leave pointed prongs. 2e; The slots 22 arealined with each other transversely jofthe bedstead, and each of theseslotshas its upper end oblique to the vertical extreme end of the shank"22 ent'ered by the slot and spaced tromthe said end by "a distancegreater than the spacing of thej'pin "5 from socket member. With theslots thus ,formed; it will i be evident from 12 jthatlthe books 24 ofthe hook member orren d piece will be wedged between the pin 5 and theback 4 of the socket member. Gravity Will continuously tend to increasethe firmness of this inter locking and the slope of the upper slotportions together With their extending beyond the pin 5 Will permit thehooks to compensate for any Wear on these parts; so that our bedsteadlock enables us to combine cheapness, firmness and durability.

However, While We have heretofore described our invention in a desirableembodiment adapted for use With bedsteads hav ing round posts andelliptical side rain, \ve do not vvish to be limited to the details otthe construction and arrangement thus disclosed. Obviously, variousadditions, omissions and otherchanges might be made Without departingfrom the spirit of our invention or 'l rom the appended claims.
